TO ALL WHOM I'l MAY CONCERN:

Beit known that I, JOHN HOLT, of Lowell, in the county of Middlesex, and State'of Massachusetts, have invented a n ew and improved Method of Making the Impression Dies whichare used for Producing the Figures in Press-Dyed Fabrlcs, which are textile fabrics colored in' part in the ordinary coloring liquidsv by being folded over a. series of-impression dies made in 'figures of ornament or otherwise, and pressed firmly together on to both sides of the fabric to keep the coloring liquid from penetrating the fabric on such partsas is desired to retain the original color in said figures of ornament; and I do hereby declare that the following is ai full, clear, andI exa'ct description,reference being had to the accompanying drawings, making part of' this specification, in which#n Figure 1 is a central longitudinal seetioirof my invention. I Y' Figure 2, ,a plan of the-lower half of' thesame. s

Figure 3, an endriew, where melted metal is poured into-the mould.

My invention consists of u metallic mould formed of two inner plates, A, and two outer plates, B, all fitted together with groot care. The inner plates are of about the same thickness, and both of these plates together must' have an equal thickness throughout their entire surfaces. Longitudinal grooves, C, and transverse grooves, f, are made in the substance ofthe inner sides of the plates A, and the grooves C are wide enough to admit of holes, e,'beirfg made'through the plates at the bottom of each groove. Either of the grooves may be made wider, and admits of a larger or a different-formed hole, that is, either square, or oblong, or curved und ornamental, so that the dies cast insaid mould will produce ornamental figures on the fabric colored by the press-dyeing process Where said dies are used. The inner plates A are arranged between the plates B on guide-pins, and when used, the plates are all put together and clamps placed thereon to hold them all firmly in place. The outer plates I3 fit very close to the outside of the platos A, and when the melted metal is poured into the mould, filling all the 'grooves C andfand the holes c, a die is formed so perfect that thirty or forty of them may he folded in with the cloth to be colored, and pressed firmly together in the coloring vat or tub and prevent the coloring liquid penetrating that portion of the cloth which comes between lthe projecting portions cast 'in the holes'c throughout the entire pack or bundle of cloth which is being colored. The bars formed by the melted metal running into the grooves C andfserve as stays and connections for the dies or ornamental impression surfaces, and muy be varied in form and size to suit the figure to be used in coloring the fabric. l

I claim the method, substantially as hereindescribed, of making the impression dies which produce the gures'in press-dyed fabrics. i
